Happy Reformation Day!

It was Saturday October 31st 1517. Martin Luther, a theology professor at Wittneberg University, was 33 years old. With a piece of paper in his hand, he walked over to the Castle church in Wittenberg, and nailed it to the door. In God's providence, this simple act became a key moment in church history. It was the moment that sparked the reformation into flame.

Today is reformation day. It is the day that the reformed church remembers Martin Luther nailing his 95 theses to the door of the church in Wittenberg, and gives thanks to our God for the impact of the reformation.

There have been quite a number of articles posted today on the significance of this simple act.
